Ito Drawing.

To all whom it may concern:

Be it known that I, HERBERT W. EAST- MAN, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new I and useful Improvements in Carbon Removers, of which the following is a specification. I This invention relates to a compound for removing carbon deposit from the cylinders of internal combustion engines, spark plugs, valves and the like,the objectbeing to provide a' compound which will free the deposit and one which when placed in the cylinder of an internal combustion engine will loosen the carbon deposit and place it in condition to be discharged or consumed in the operation of the engine.

The carbon compound is formed of alcohol, acetone, sulphuric ether, stronger am-. monia water, and chloroform, which are thoroughly mixed and let stand for fortyeight hours to allow several chemical reactons to take place between the ingredients of the composition. One gallo of alcohol is added to the ether before mixing all of the other ingredients. The composition is then filtered and placed in bottles and is ready to be used by placing a small portion 80 of the same in the cylinder of an internal combustion engine for removing the carbon therefrom, or a valve or s ark plu can be immersed in the composition which will gallons of chloroform.

Alcohol 80 gallons Acetone 15 gallons Sulphuric ether 4 gallons Stronger ammonia water 100 gallons Chloroform 4 gallons In mixing the ingredients they are preferably placed in the container and mixed together in the order named, and before the ether is placed in a gallon of (alcohol is mixed with the same. The solution of ammonia used is preferably 26 per cent.

What I claim is A carbon removing composition consist- 'ing of gallons of alcohol, 15 gallons of acetone, 4 gallons of sulphuric ether, gallons of stronger ammonia water, and 4 00 In testimony whereof I hereunto aflix 'm resence of two witnesses, HER ERT W. EASTMAN.
